' INTERCHANGEABLE NEEDLE-GUIDE.

To all whom it may concern:

-Be it known that I, WILLIAM L. BARRON, acitizen of the United "States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvementsv in Interchangeable.

' theaccompanying drawings.

This invention relates to needle-guides and more particularly toguides for-'use in chain stitchmachines to prevent the needles from beingv deflected intovthe path of the loopers.

-The objects of the invention are to provide. means whereby the guides-maybe in terchanged, their relative order varied, their position changed transversely or longitudinally relatively to the seam line, or their position changedrelatively to each other, according to the requirements of varying needle positions. v

The present embodiment comprises a needle-guide support adjustably mounted on the'machine frame, and a plurality of needleguides interchangeably mounted'on said support; the guides being adjustable in a direction at; an angle to the direction in which the support isadjusted,

their arrangement and that of the loopers.

Fig. 2 is a view similar to Fig. 1 showing the needles as staggered in a directionopposite to that in Fig. 1. Fig. 2 is a section through the needles in Fig. 2, showing their arrangement and thatof the loopers. Fig. 3 is a view similar to Fig. 1 showing an adjustable guide applied to needles arranged abreast. Fig. 3 is a section through the needles and above the looper in Fig. 8. Fig. 4: is a perspective view of the needle-guide support. Fig. 5 is a perspective view of one of the needle-guides. Figs. 6 and 7 are perspective views of guides cooperating with that shown in Fig. 5. Fig. 8 is a perspective view of the guide represented in Fig. 3.

' Specification of Letters Patent.

and adj ustably Referringto the drawings, 1 indicates a lug on the machine frame. A needle-guide support 2 is adjustably mounted on the lug by means ofa slot 3 in the support and a screw 4; passing through the slot and engagingthe lug 1. At the forward oflset end of the support-'2 a groove 5 is formed in which the various needle-guides are adjustably and interchangeably secured by means offthe screw 6. A feed-dog 6, having the usual feed Land lift movements, extends parallel to the line of seam-formation.

.In'Fig. 1 the needles 7 and 8 are shown as staggered, as are their corresponding cent the needle-8, and a horizontalportion arranged in the groove 5 of the support 2.

. WILLIAM L. BARRON, or NEWARK, new JERSEY, AssreNoR TO THE SQINGERHMANUL A closed slot 10 is formed in the horizontal portion ofthe guide "9. A second angled needle-guide ll' has a vertical guide porportion arranged in the groove 5 and in formed in said horizontal porition. guides are: spaced apart longitudinally of theseam line by a-small projection or spacer 13 which in, the present instance and pref tion adjacent the needle 7, and a horizontal erablyis formed integral with the guide 11., I

The:guides'are secured in the groove- 5 by the screw 6 which passes through the slots 10 and 12.

In Fig. 2 the needles 14 and 15 are also arranged in staggered relation, but the right-hand needle 15 is in front. In this case the right-hand needle guide 9 is also arranged in front and the-left-hand guide 11 in the rear, the spacing projection 13 being then arranged on the'opposite sideof 1 guide 11, as shown in Figs. 2' and 7.

In Fig. 3 the needles l6 and 17 are shown as arranged abreast, with a single coiiperating looper 18.

A single angled needleguide 19 may then be'used, its enlarged vertical portion being disposed adjacent the needles, and its horizontal portion fitting in the slot 5 of the support. The closed slot 20 allows the guide to be adjustably secured by means of the screw 6.

By applicants construction a few parts suflice for a large number of different needle art constructions of providing a very large number of needle guides for the same purose.

p Having thus set forth the nature of the invention, what I claim herein is- 1. In a sewing machine, a reciprocating needle, and a guide therefor adjustable in a single movement transversely of both the needle-path and the line of seam-formation.

2. In a sewing machine, a reciprocating needle, and a needle-guide having an adjustment longitudinally of the line of seamformation and having a second adjustment transversely of both the needle-path and the line of seam-formation.

3. In a sewing machine, reciprocating needles, an adjustable support, and needleguide means carried by said support and 7 adjustable horizontally of said support and transversely of the seam line.

4. In a sewing machine, reciprocating needles, and needle-guides therefor adjustable transversely relatively to the seam line and also adjustablerelatively to each other.

5. In a sewing machine, an adjustable needle-guide support, and means for interchangeably and adjustably securing a pluralityof needle-guides thereto.

6. In a sewing machine, a plurality of needles in staggered relation, needle-guides therefor, and means whereby said guides may be adjusted laterally of the seam line.

7 In a sewing machine, a plurality of needles in staggered relation, needle-guides therefor, means whereby said guides may be adjusted relatively to said needles and also to each other, and means for adjusting said guides longitudinally of the seam line.

8. In a sewing machine, a plurality of needles in staggered relation, a needle-guide support adjustable longitudinally of the seam line, and needle-guides disposed transversely of the seam line and individually and simultaneously adjustable with respect to said support.

9. In a sewing machine, a plurality of reciprocating needles, an adjustable needleguide support, a plurality of needle-guides,

and means for securing said guides in said support in varylng relation to each other and to said support, whereby the guides may be properly located for different needle posi-.

needles and also to each other. 7

11. In a sewing machine, a plurality of reciprocating needles in staggered relation, a plurality of needle guides, means carried by one of said guides for spacing them longitudinallyof the seam line, and'means whereby said guides may be adjusted transversely of the seam line and needle-paths.

12. In a sewing machine, aneedle, a looper, and a guide for the needle adjustable substantially longitudinally of the looper path.

13. In a sewing machine, a plurality of needles, guides therefor and means whereby said guides may be adjusted relatively to the needles and to each other.

14. In a sewing machine, va plurality of needles, guides therefor, and means for in- V terchangeablymounting said guides.

15. In a sewing machine, an adjustable needle-guide support, a plurality of needle guides, and means for mounting the guides on the support so that they may be adjusted relatively to .eachother.

In testimony whereof, I have signed my name to this specification.
